Background. Ankle fractures associated with diabetes experience more complications following standard Open-Reduction-Internal-Fixation (ORIF) than those without diabetes. Augmented fixation strategies namely extended ORIF and hind-foot-nail (HFN) may offer better results, and early weightbearing in this group. The aim of this study was to define the population of patients with diabetes undergoing primary fixation for ankle fractures. Secondarily, to assess the utilisation of standard and augmented strategies and the effect of these choices on surgical outcomes including early post-operative weight bearing and surgical complications. Methods. A national-multicentre retrospective cohort study was conducted between January to June 2019 in 56 centres (10 Major- Trauma-Centres and 46 Trauma-Units) in the United Kingdom; 1360 specifically defined complex ankle-fractures were enrolled. Demographics, fixation choice, surgical and functional outcomes were recorded. Statistical analysis was performed to compare high-risk patients with/without diabetes. Results. There were 316 patients in the diabetes cohort with mean age 63.9yrs (vs. 49.3yrs in non-diabetes cohort), and greater frailty score >4 (24% vs.14% (non-diabetes cohort) (p<0.03); 7.5% had documented neuropathy. In the diabetes cohort, 79.7% underwent standard ORIF, 7.1% extended ORIF and 10.2% a HFN compared to 87.7%, 3.0% and 10.3% in the non-diabetes cohort. Surgical wound complications after standard-ORIF were higher in the diabetes cohort (15.1% vs. 8.7%) (p<0.02) but patients with diabetes who underwent augmented techniques showed little difference in surgical outcomes/complications to non-diabetes, even though early-weight- bearing rates were greater than standard-ORIF. Conclusion. Ankle fractures in diabetes occur in older, frailer patients; whilst lower than expected neuropathy rates suggest a need for improved assessment. Augmented surgical techniques may allow earlier weight-bearing without increasing complications in keeping with modern guidelines in ankle fracture management

Introduction. Severe, multiplanar, fixed, pantalar deformities present a challenge to orthopaedic surgeons. Surgical options include limb salvage or amputation. This study compares outcomes of patients with such deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). Methods. Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17 to 72 years) and median follow-up duration was 49.9 months (18.0 to 253.7 months). Patients with chronic regional pain syndrome, tumour, acute trauma or diabetic Charcot arthropathy were excluded. Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgical outcome and whether they would have the same surgery again. Results. There was no statistically significant difference in patient reported outcomes, satisfaction, or complication profile between the groups. Twenty-two patients undergoing PTF (81.5%), 6 patients undergoing TCF (75%), and 15 patients undergoing BKA (93.8%) were satisfied overall (p=0.414). Similarly, there was no difference in the proportion of patients who would opt for the same procedure again (p=0.142): 23 in the PTF group (85.2%), 8 in the TCF group (100%), and 11 in the BKA group (68.8%). Seven patients undergoing PTF (25.9%), 2 patients undergoing TCF (25%) and 6 patients undergoing BKA (37.5%) had major complications (p=0.692). Conclusion. This study has shown that PTF, TCF and BKA can all provide an acceptable outcome in treatment of severe, degenerative deformities of the lower extremity. Therefore, surgical decisions must be based on individual patient considerations. This data may also be useful in counselling patients when considering limb salvage versus amputation for severe deformity

Background. Hallux rigidus is a common condition characterised by first metatarsophalangeal joint (MTPJ) degeneration, pain and limited range of motion (ROM). The gold standard surgical treatment is arthrodesis, providing good pain relief but sacrifices ROM. Recently the Cartiva synthetic cartilage implant (SCI) has been utilised as an interpositional arthroplasty, aiming to reduce pain whilst preserving range of motion. Current evidence for Cartiva SCI is largely based on a single cohort with mixed outcomes. We sought to evaluate the clinical outcomes of Cartiva SCI compared to arthrodesis undertaken in our centre. Methods. Retrospective review of patients undergoing Cartiva SCI or arthrodesis for treating hallux rigidus was conducted. Preoperative arthritis was radiographically graded using the Vanore classification. Patient reported outcomes (PROMs) were assessed using EuroQol 5-dimension score (EQ-5D-5L) and Manchester-Oxford Foot Questionnaire (MOXFQ). Results. Between 2017 and 2020 there were 33 cases (17 Cartiva, 16 arthrodesis, mean age 59.0±9.9 years) with a mean follow up of 2.3 years. For the first MTPJ arthrodesis cohort, the MOXFQ domain scores were: Index 3.9±5.8, Walking/Standing 5.1±7.6, Pain 3.2±5.0, and Social Interaction 2.6±4.0. EQ-5D-5L Index score was 0.828±0.270 and the EQ-VAS was 72.5±23.3. For the Cartiva cohort, the MOXFQ domain scores were: Index 7.7±6.0, Walking/Standing 8.9±7.9, Pain 7.1±5.0, and Social Interaction 6.4±5.4. EQ-5D-5L Index score was 0.631±0.234 and the EQ-VAS was 74.8±20.8. There was no statistically significant difference between any MOXFQ domain or EQ-5D-5L scores. However, a negative trend in MOXFQ domains was identified for the Cartiva group, as well as a reoperation rate of 23.5%. Conclusions. The Cartiva SCI demonstrated no advantage over arthrodesis in PROMs, despite the presumed benefit of preserved ROM. A significant reoperation rate was also observed. Surgeons should be cautious in the use of this novel implant

One assumed function of Total Ankle Replacement (TAR) is that by maintaining ankle joint motion we can protect the other hind foot joints from further degredation. 1. However, there is no work to our knowledge that compares hindfoot outcomes between TAR and arthrodesis. Sokolowski et al. found that 68% of TAR patients had no radiological progression of subtalar arthritis after TAR, and 4% went on to fusion. 2. However, no evaluation of the other hindfoot joints was made and no comparison made to other treatment. We performed a retrospective review of all patients at our centre who had had a TAR or ankle arthrodesis since 2002. Case notes and imaging were reviewed and all instances of hindfoot treatment (injections or surgical procedures) noted. Patients were excluded who had no documentation, were followed up at other hospitals, had prior hindfoot fusion, or were having staged surgeries at the time of index treatment. Chi squared analysis was used to compare the cohorts. 214 arthrodesis cases and 302 TAR were eligible. The average age was 57. Average time to follow up was 13 years (4–21). At the time of abstract submission 107 sets of notes had been reviewed fully. Full analysis will be performed by conference. 14% of TAR patients went on to have further procedures to the hindfoot joints while 35% of arthrodesis patients had further procedures (p=0.014). There was also a significant difference in the number of patients progressing to fusion of a further hindfoot joint between groups (TAR- 4%, arthrodesis- 20%, p=0.01). These data suggest that TAR are protective of symptomatic change of hindfoot joints. Patients with TAR had fewer hindfoot fusions than those with arthrodesis and also fewer procedures of any form, including injections

Introduction. Acute ankle injuries are commonly seen in musculoskeletal practice. Surgical management is the gold standard for lateral ligament injury in those with failed conservative treatment for a minimum of six months. Several studies have shown good functional outcome and early rehabilitation after MBG repair with an internal brace augmentation which is a braided ultrahigh molecular weight polyethylene ligament used to enhance the repair that acts as a secondary stabiliser. Hence the aim of the study was to compare the results with and without augmentation. Methods. A single centre retrospective review conducted between November 2017 and October 2019 and this included 172 patients with symptomatic chronic lateral ligament instability with failed conservative management. The diagnosis was confirmed by MRI. All patients had an ankle arthroscopy followed by open ligament repair. Patients were grouped into isolated MBG and internal brace groups for analyses and all had dedicated rehabilitation. Results. A total of 148 patients were available for final follow up with 87 patients in the MBG group and 61 patients in the IBA group. Mean Age was 38 years and mean follow up was 22 months. The internal brace group showed better Manchester Oxford foot and ankle score (19.7 vs 18.2) and more patients returning to preinjury activity levels (73 vs 55) as compared to isolated repair. Conclusion. Internal brace augmentation with MBG repair facilitated early rehabilitation and return to pre injury activity level in majority of patients compared to isolated MBG repair

Background. In fixation of the fibula in ankle fractures, AO advocate using a lag screw and one-third tubular neutralisation plate for simple patterns. Where a lag screw cannot be placed, bridging fixation is required. A local pilot service evaluation previously identified variance in use of locking plates in all patterns with significant cost implications. The FAIR study aimed to evaluate current practice and implant use across the United Kingdom (UK) and review outcomes and complication rates between different fibula fixation methods. Method. The study was supported by CORNET, the North East trainee research collaborative, and BOTA. Data was collected using REDCap from 22 centres in the UK retrospectively for a one-year period between 1. st. January 2019 and 31. st. December 2019 on injury mechanism, fracture characteristics, comorbidities, fixation and complications. Follow-up data was collected to at least two-years from the time surgery. Results. 1448 ankle fractures which involved fixation of the fibula were recorded; one-third tubular plate was used in 866 (59.8%) cases, a locking plate in 463 (32.0%) cases and other methods in 119 (8.2%) cases. There was significant difference between centres (p<0.001) in implant type used. Other factors associated with implant type were age, diabetes, osteoporosis, open fractures, fracture pattern and the presence of comminution. Incidence of lateral wound breakdown was higher in locking plates than one-third tubular plates (p<0.05). There was no significant difference in infection, non-union, fixation failure or removal of metalware. Conclusion. There is significant variation in practice in the UK in implant use for fixation of the fibula in ankle fractures. Potentially unnecessary use of locking plates, where a one-third tubular shows equivalent outcomes, incurs additional cost and may increase the risk of lateral wound breakdown. We would encourage surgeons with high locking plate usage to evaluate their own unit's practice against this data

Aims. The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications. Methods. Between September 2014 and July 2017, 25 patients with symptomatic osteochondritis of the talus and an osteochondral fragment, who were treated using bone peg fixation, were analyzed retrospectively. All were available for complete follow-up at a mean 22 of months (12 to 35). There were 15 males and ten females with a mean age of 19.6 years (11 to 34). The clinical results were evaluated using a visual analogue scale (VAS) and the American Orthopaedic Foot and Ankle Society (AOFAS) score preoperatively and at the final follow-up. The radiological results were evaluated using classification described by Hepple et al based on the MRI findings, the location of the lesion, the size of the osteochondral fragment, and the postoperative healing of the lesion. Results. The mean VAS and AOFAS score improved significantly from 6.3 (4 to 8) and 70.6 (44 to 78) preoperatively to 1.6 (0 to 5) and 91.1 (77 to 100) at the final follow-up, respectively (p < 0.001). The classification on MRI was stage 2a in nine patients, stage 3 in 14, and stage 4 in two. The lesion was located on the posteromedial aspect of the dome of the talus in 19 patients, the anterolateral aspect in five, and the centrolateral aspect in one. The mean size of the fragment was 11.2 mm (5 to 20) horizontally, 10.4 mm (7 to 18) vertically, and 5.2 mm (3 to 10) deep, respectively. The postoperative healing state was good in 19 patients and fair in six. Conclusion. Bone peg fixation for osteochondral lesions of the talus showed satisfactory clinical and radiographic results, without complications. This technique could be a good form of treatment for patients with this condition who have an osteochondral fragment. Cite this article: Bone Joint J 2020;102-B(10):1349–1353

Aims. To our knowledge, there is currently no information available about the rate of venous thromboembolism (VTE) or recommendations regarding chemoprophylaxis for patients whose lower limb is immobilized in a plaster cast. We report a retrospective case series assessing the rate of symptomatic VTE in patients treated with a lower limb cast. Given the complex, heterogeneous nature of this group of patients, with many risk factors for VTE, we hypothesized that the rate of VTE would be higher than in the general population. Patients and Methods. Patients treated with a lower limb cast between 2006 and 2018 were identified using plaster room records. Their electronic records and radiological reports were reviewed for details about their cast, past medical history, and any VTE recorded in our hospital within a year of casting. Results. There were 136 episodes of casting in 100 patients. The mean age was 55 years (22 to 91). The mean time in a cast was 45 days (five days to eight months). A total of 76 patients had neuropathy secondary to diabetes. No patient received chemical thromboprophylaxis while in a cast. One VTE (0.7% of casting episodes) was documented. This was confirmed by Doppler scan nine days after removing the cast. Conclusion. The frequency of VTE was higher than that of the general population (0.05%); this is most likely attributable to our patients’ apparent increase in VTE risk as suggested by The National Institute for Health and Care Excellence (NICE). These findings suggest that thromboprophylaxis is not routinely indicated in patients who undergo immobilization of the lower limb in a cast, although the risks of VTE should be assessed. While the cast itself does not pose an increased risk, other pathologies, such as active cancer, mean that each individual case needs to be considered on their merit.

Introduction:. Patient reported outcome measures are becoming more popular in their use. Retrospective scoring is not yet a validated method of data collection but one that could greatly decrease the complexity of research projects. We aim to compare preoperative and retrospective scores in order to assess their correlation and accuracy. Methods:. 36 patients underwent elective foot and ankle surgery. All patients were scored preoperatively using the SF-12 and FFI. Patients then recorded both PROMs retrospectively at the three month follow up (av. 139 days). Results were then analyzed for statistical significance. Results:. 36 patients (av. age 54.6 years) completed both sets of questionnaires. There were 15 hindfoot and 21 forefoot procedures. Two patients (5.6%) recalled their identical preoperative SF12 score. No retrospective FFI scores were identical. The mean percentage difference between the two preoperative scores was; −0.9% (−5.8 to 4.0%, 95% CI) for SF12 and 40.7% (25.3 to 56.1%, 95% CI) for FFI. This retrospective accuracy was statistically significant (p< 0.001). When both scores were plotted against each other, the outcome measurements showed positive correlations (SF 12 p 0.31, FFI p 0.81). With both PROMs mean percentage differences combined, patients undergoing hindfoot procedures (13.5%; 5.8 to 21.3%, 95% CI) were more accurate with retrospective scoring than their forefoot counterparts (26.8%; 10.4 to 43.1%, 95% CI). This was not statistically significant. Conclusion:. Retrospective scoring appears to lack accuracy when compared to prospective methods. However, our data shows the SF12 is recalled more accurately than the FFI (p< 0.001) and to an average discrepancy of < 1% when compared to the original preoperative result. These results show patients tend to recall their symptoms at a worse level preoperatively than originally described, especially those with forefoot problems

Introduction. Venous thromboembolism (VTE) represents a major cause of morbidity, mortality and financial burden to the NHS. Acquired risk factors are well documented, including immobilisation, lower limb plaster cast and surgery. NICE guidance on VTE prophylaxis within orthopaedics currently excludes operative ankle fracture fixation (ankle ORIF). Aims. Ascertain the local incidence of VTE; compare our local VTE rates with published data from other institutions; review guidelines, scientific literature and other hospitals policies; formulate a local policy for VTE prophylaxis. Method. Retrospective analysis of records of all patients undergoing ankle ORIF in our hospital over a continuous 5 year period, identifying cases of VTE, individual risk factors and surgical duration. Results. 380 patients underwent ankle ORIF; 3 developed VTE; no mortality. VTE incidence 0.79% (0.26%DVT; 0.53%PE). Operative duration 88 +/− 34mins (mean +/− 1S.D); in those with VTE, duration was 35, 90&85min. There is no statistically significant difference (p=0.18) observed between our local and national VTE incidence rates. Operative duration was not a significant factor in those developing VTE. Additional risk factors were identified in one patient with VTE. Discussion. The incidence of heparin induced thrombocytopenia is 0.5%, its associated mortality 10% (i.e. 1:2000). To prevent one fatal PE in foot & ankle surgery, 10,000 must receive VTE prophylaxis. Therefore, heparin associated mortality exceeds VTE associated mortality in foot & ankle surgery. Conclusion. Our local VTE rates are comparable to national rates. Risk of pharmacological prophylaxis exceeds benefit; therefore routine use not justified. Individual risk should be assessed; higher risk patients may benefit

Introduction. Ankle replacement is a major surgery with significant soft tissue dissection and bleeding. The skin quality is often poor in these patients due to age, edema, venous congestion, arteriopathy or previous procedures and soft tissue injury. The chances of wound infection increase with delayed wound healing. Absorbent non-adherent dressing (ABD) and VAC dressing applied in theatre after ankle replacement were assessed in a cohort of 147 patients with wound complications, pain, satisfaction and length of stay as outcome measures. Patients and methods. 71 consecutive patients were treated with ABD post-operatively after ankle replacement. The practice was then changed to VAC dressings for 76 consecutive patients. 44 patients had additional procedures performed with ankle replacement (11 from ABD group and 33 from VAC group). Retrospective analysis of prospectively collected data was performed. All patients had daily pain score, wound status, hospital stay, satisfaction and range of movement recorded. Results. Patients with VAC had mean pain score of 3/10 post operatively compared with 6/10 with ABD. There was a significant difference between the length of stay between the groups (p=0.02). The average stay of stay was 9 days with ABD and 7 days with VAC dressing. One of the patients with VAC dressing had blisters and 1 patient developed a superficial wound infection. Of the ABD group, 3 patients developed blisters and 7 patients had wound complications after ABD. Range of movement was similar in both groups of patients. Patient's satisfaction with VAC dressing was 8/10. Conclusion. VAC is better than ABD as primary dressing after ankle replacement

Aim. This retrospective case series reports the reoperation, major amputation, survival rates and mobility status in diabetic patients who underwent a trans-metatarsal amputation (TMA) managed within a multi-disciplinary diabetic foot care service. Methods and patients. Forty-one consecutive patients (37 men, 4 women) underwent a TMA between January 2008 to December 2017. They were retrospectively reviewed. The mean age at the time of surgery was 63 years (range 39 – 92). Results. Eighty-eight per cent (36/41) of the patients were followed-up. Four (11%) of the 36 patients required reoperation, including three major amputations (8%). All the patients requiring a reoperation were vasculopaths. The four-year patient survival rate following a TMA was 69% (25/36). Ninety-six per cent (21/22) of the surviving patients not requiring revision to a major amputation were fully mobile in bespoke orthoses, of whom a third required a stick. Conclusion. This study shows that transmetatarsal amputation in patients with diabetes, managed in a multi-disciplinary diabetic foot care service, is effective for limb salvage

Objectives. The primary aim was to determine the differences in COVID-19 infection rate and 30 day mortality in patients undergoing foot and ankle surgery between different treatment pathways over the two phases of the UK-FALCON audit, spanning the first and second national lockdowns. Design. Multicentre retrospective national audit. Setting. This was a combined retrospective (Phase 1) and prospective (Phase 2) national audit of foot and ankle procedures in the UK in 2020. Participants. All adult patients undergoing foot and ankle surgery in an operating theatre during the study period included from 46 participating centres in England, Scotland, Wales and Northern Ireland. Patients were categorised as either a green pathway (designated COVID-19 free) or blue pathway. Results. 10,846 patients were included, 6,644 from phase 1 and 4,202 from phase 2. Over the 2 phases the infection rate on a blue pathway was 1.07% (69/6,470) and 0.21% on a green pathway (9/4,280). In phase 1, there was no significant difference in the COVID-19 perioperative infection rate between the blue and green pathways in any element of the first phase (pre-lockdown (p = .109), lockdown (p = .923) or post-lockdown (p = .577)). However, in phase 2 there was a significant reduction in perioperative infection rate when using the green pathway in both the pre-lockdown (p < .001) and lockdown periods (p < .001). There was no significant difference in COVID-19 related mortality between pathways. Conclusions. There was a five-fold reduction in the perioperative COVID-19 infection rate when using designated COVID-19 green pathways; however the success of the pathways only became significant in phase 2 of the study. The study shows a developing success in using green pathways in reducing the risk to patients undergoing foot and ankle surgery

Aims. Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation. Methods. This retrospective cohort study analyzed a total of 43,287 patients from national health claims data spanning 2008 to 2018, focusing on patients who underwent surgical treatment for primary Achilles tendon rupture. Short-term ATRR was defined as cases that required revision surgery occurring between six weeks and one year after the initial surgical repair, while omitting cases with simultaneous infection or skin necrosis. Variables such as age, sex, the presence of Achilles tendinopathy, and comorbidities were systematically collected for the analysis. We employed multivariate stepwise logistic regression to identify potential risk factors associated with short-term ATRR. Results. From 2009 to 2018, the short-term re-rupture rate for Achilles tendon surgeries was 2.14%. Risk factors included male sex, younger age, and the presence of Achilles tendinopathy. Conclusion. This large-scale, big-data study reaffirmed known risk factors for short-term Achilles tendon re-rupture, specifically identifying male sex and younger age. Moreover, this study discovered that a prior history of Achilles tendinopathy emerges as an independent risk factor for re-rupture, even following initial operative fixation.

Aims. Osteochondral lesions of the talus (OLT) are a common cause of disability and chronic ankle pain. Many operative treatment strategies have been introduced; however, they have their own disadvantages. Recently lesion repair using autologous cartilage chip has emerged therefore we investigated the efficacy of particulated autologous cartilage transplantation (PACT) in OLT. Methods. We retrospectively analyzed 32 consecutive symptomatic patients with OLT who underwent PACT with minimum one-year follow-up. Standard preoperative radiography and MRI were performed for all patients. Follow-up second-look arthroscopy or MRI was performed with patient consent approximately one-year postoperatively. Magnetic resonance Observation of Cartilage Repair Tissue (MOCART) score and International Cartilage Repair Society (ICRS) grades were used to evaluate the quality of the regenerated cartilage. Clinical outcomes were assessed using the pain visual analogue scale (VAS), Foot Function Index (FFI), and Foot Ankle Outcome Scale (FAOS). Results. All patients had ICRS grade IV cartilage lesions, except for one (ICRS grade III). The paired MOCART scores significantly improved from 42.5 (SD 1.53) to 63.5 (SD 22.60) (p = 0.025) in ten patients. Seven patients agreed to undergo second-look arthroscopy; 5 patients had grade I (normal) ICRS scores and two patients had grade II (nearly normal) ICRS scores. VAS, FFI, and all subscales of FAOS were significantly improved postoperatively (p ≤ 0.003). Conclusion. PACT significantly improved the clinical, radiological, and morphological outcomes of OLT. We consider this to be a safe and effective surgical method based on the short-term clinical results of this study. Cite this article: Bone Jt Open 2023;4(12):942–947

Aims. Implant failure has become more common as the number of primary total ankle arthroplasties (TAAs) performed has increased. Although revision arthroplasty has gained attention for functional preservation, the long-term results remain unclear. This study aimed to assess the long-term outcomes of revision TAA using a mobile-bearing prosthesis in a considerably large cohort; the risk factors for failure were also determined. Methods. This single-centre retrospective cohort study included 116 patients (117 ankles) who underwent revision TAA for failed primary TAA between July 2000 and March 2010. Survival analysis and risk factor assessment were performed, and clinical performance and patient satisfaction were evaluated preoperatively and at last follow-up. Results. The mean duration from initial revision TAA to last follow-up was 15.0 years (SD 3.0; 11.2 to 20.5). The cumulative survival rates of the revised ankles were 81% (95% confidence interval (CI) 74% to 88%), 74% (65% to 82%), and 70% (61% to 79%) at five, ten, and 15 years, respectively. Comorbidities prior to primary TAA, aseptic loosening, instability, or grafting of cysts were found to be the most common risk factors for secondary revision. The median value for preoperative pain, as assessed using the visual analogue scale, declined from 6 (interquartile range (IQR) 5 to 8) to 2 (IQR 0 to 5) (p < 0.001) and the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from 43 (SD 17) preoperatively to 70 (SD 20) (p < 0.001) at last follow-up. Conclusion. Revision TAA offers acceptable survival rates after 15 years; it therefore offers a valuable option for treatment of implant failure in carefully selected cases. Although patient-reported outcomes improve substantially, the degree of improvement reported following primary TAA is not achieved. Cite this article: Bone Joint J 2024;106-B(1):46–52

Aims. This study evaluated the effect of treating clinician speciality on management of zone 2 fifth metatarsal fractures. Methods. This was a retrospective cohort study of patients with acute zone 2 fifth metatarsal fractures who presented to a single large, urban, academic medical centre between December 2012 and April 2022. Zone 2 was the region of the fifth metatarsal base bordered by the fourth and fifth metatarsal articulation on the oblique radiograph. The proportion of patients allowed to bear weight as tolerated immediately after injury was compared between patients treated by orthopaedic surgeons and podiatrists. The effects of unrestricted weightbearing and foot and/or ankle immobilization on clinical healing were assessed. A total of 487 patients with zone 2 fractures were included (mean age 53.5 years (SD 16.9), mean BMI 27.2 kg/m. 2. (SD 6.0)) with a mean follow-up duration of 2.57 years (SD 2.64). Results. Overall, 281 patients (57.7%) were treated by orthopaedic surgeons, and 206 patients (42.3%) by podiatrists. When controlling for age, sex, and time between symptom onset and presentation, the likelihood of undergoing operative treatment was significantly greater when treated by a podiatrist (odds ratio (OR) 2.9 (95% CI 1.2 to 8.2); p = 0.029). A greater proportion of patients treated by orthopaedic surgeons were allowed to immediately bear weight on the injured foot (70.9% (178/251) vs 47.3% (71/150); p < 0.001). Patients treated by podiatrists were immobilized for significantly longer (mean 8.4 weeks (SD 5.7) vs 6.8 weeks (SD 4.3); p = 0.002) and experienced a significantly longer mean time to clinical healing (12.1 (SD 10.6) vs 9.0 weeks (SD 7.3), p = 0.003). Conclusion. Although there was considerable heterogeneity among zone 2 fracture management, orthopaedic surgeons were less likely to treat patients operatively and more likely to allow early full weightbearing compared to podiatrists.

Aims. The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant. Methods. This is a single-centre retrospective review of patients who underwent primary total ankle arthroplasty (TAA) with a Vantage implant between November 2017 and February 2020, with a minimum of two years’ follow-up. Four surgeons contributed patients. The primary outcome was reoperation and revision rate of the Vantage implant at two years. Secondary outcomes included radiological alignment, peri-implant complications, and pre- and postoperative patient-reported outcomes. Results. There were 168 patients (171 ankles) included with a mean follow-up of 2.81 years (2 to 4.6) and mean age of 63.0 years (SD 9.4). Of the ten ankles with implant failure (5.8%), six had loosening of the tibial component. In the remaining four failed implants, one was due to periprosthetic joint infection (PJI), one was due to loosening of the talar component, and two were due to loosening of both the tibial and talar components. Seven patients underwent reoperation: irrigation and debridement for superficial infection (n = 4); bone grafting for cysts (n = 2); and open reduction internal fixation (n = 1). Asymptomatic peri-implant lucency/subsidence occurred in 20.1% of ankles, with the majority involving the tibial component (n = 25). There were statistically significant improvements in PROMs in all domains. Conclusion. Short-term results of this implant demonstrate early survival comparable to the reported survivorship of similar low-profile, non-stemmed implants. Radiological lucency occurred more commonly at the tibial component, and revisions occurred primarily due to loosening of the tibial component. Further research is needed to evaluate longer-term survivorship. Cite this article: Bone Joint J 2023;105-B(10):1099–1107

Aims. The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques. Methods. We conducted a comprehensive review of clinical trials comparing anteroposterior (A-P) screws, posteroanterior (P-A) screws, and plate fixation. Two investigators validated the data sourced from multiple databases (MEDLINE, EMBASE, and Web of Science). Following PRISMA guidelines, we carried out a network meta-analysis (NMA) using visual analogue scale and American Orthopaedic Foot and Ankle Score (AOFAS) as primary outcomes. Secondary outcomes included range of motion limitations, radiological outcomes, and complication rates. Results. The NMA encompassed 13 studies, consisting of four randomized trials and eight retrospective ones. According to the surface under the cumulative ranking curve-based ranking, the A-P screw was ranked highest for improvements in AOFAS and exhibited lowest in infection and peroneal nerve injury incidence. The P-A screws, on the other hand, excelled in terms of VAS score improvements. Conversely, posterior buttress plate fixation showed the least incidence of osteoarthritis grade progression, postoperative articular step-off ≥ 2 mm, nonunions, and loss of ankle dorsiflexion ≥ 5°, though it underperformed in most other clinical outcomes. Conclusion. The NMA suggests that open plating is more likely to provide better radiological outcomes, while screw fixation may have a greater potential for superior functional and pain results. Nevertheless, clinicians should still consider the fragment size and fracture pattern, weighing the advantages of rigid biomechanical fixation against the possibility of soft-tissue damage, to optimize treatment results.

Aims. Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below-knee amputation, particularly in the presence of severe soft-tissue destruction. This study assesses the outcomes of single-stage orthoplastic surgical treatment of calcaneal osteomyelitis with large soft-tissue defects. Methods. A retrospective review was performed of all patients who underwent combined single-stage orthoplastic treatment of calcaneal osteomyelitis (01/2008 to 12/2022). Primary outcome measures were osteomyelitis recurrence and below-knee amputation (BKA). Secondary outcome measures included flap failure, operating time, complications, and length of stay. Results. A total of 30 patients (14 female, 16 male; mean age 53.7 years (95% CI 48.0 to 59.5)) underwent combined orthoplastic surgical treatment for BACH “complex” calcaneal osteomyelitis with a median follow-up of 31 months (IQR 11.75 to 49.25). Of these, 19 received a local flap and 11 received a free flap. The most common causes were fracture-related infection (n = 12; 40%) and ulceration (n = 10; 33%); 21 patients (70%) had already undergone at least one operation elsewhere. Osteomyelitis was eradicated in 23 patients (77%). There were seven patients who developed recurrent osteomyelitis (23%), all in the local flap group. One patient required a BKA. Univariate analysis revealed that local flap reconstruction (OR 13.5 (95% CI 0.7 to 269.7); p = 0.029) and peripheral vascular disease (OR 16.5 (95% CI 1.35 to 203.1); p = 0.008) were associated with increased risk of recurrence. Free flap reconstruction took significantly longer intraoperatively than local flaps (mean 481 minutes (408 to 554) vs mean 168 minutes (119 to 216); p < 0.001), but without significant differences in length of stay or frequency of outpatient appointments. Conclusion. In our study involving 30 patients, single-stage orthoplastic management was associated with 77% (n = 23) eradication of infection and only one amputation in this complex and comorbid patient group. Risk factors for failure were peripheral vascular disease and local flap reconstruction. While good outcomes can be achieved, this treatment requires high levels of inpatient and outpatient care.
